       6. The back plate according to  claim 1 , wherein the back plate comprises a bending area and a non-bending area, which are disposed adjacent to each other, and a gap between adjacent ones of the framework strips in the bending area is larger than a gap between adjacent ones of the framework strips in the non-bending area. 
     
     
       7. The back sheet according to  claim 6 , wherein the framework layer is formed on the first surface by screen printing. 
     
     
       8. The back sheet according to  claim 7 , wherein the polymer comprises polyimide, ethylene phthalate, and a cured glue. 
     
     
       9. The back sheet according to  claim 1 , wherein the filling layer is made of a material comprising at least one of polyimide and ethylene phthalate. 
     
     
       10. A display device, comprising a panel, a flip-chip thin film substrate, a flexible circuit board, a polarizer, an optical adhesive layer, a cover window, and a back plate, wherein the panel covers the back plate, an end of the panel is connected to the flexible circuit board through the flip-chip thin film substrate, the polarizer covers at least a part of the panel, the optical adhesive layer covers the polarizer, and the cover window covers the optical adhesive layer, wherein the back plate comprises:
 a flexible layer having a first surface and a second surface opposite to each other; 
 a framework layer disposed on the first surface, and comprising at least two framework strips which are spaced apart from each other, wherein the framework layer is made of a material comprising a polymer; and 
 a filling layer covering a side of the framework layer away from the flexible layer, and embedded in a gap between adjacent ones of the framework strips. 
 
     
     
       11. The display device according to  claim 10 , wherein the framework strips are arranged at intervals along a first direction of the flexible layer and extend in a second direction of the flexible layer. 
     
     
       12. The display device according to  claim 11 , wherein the framework strips are arranged at intervals along the second direction and extend in the first direction, and wherein a grid structure is formed by the framework strips arranged at intervals along the first direction and extending in a second direction and the framework strips arranged at intervals along the second direction and extending in the first direction. 
     
     
       13. The display device according to  claim 10 , wherein an elastic modulus of the framework layer is greater than an elastic modulus of the filling layer.
